Overview

This repo contains the bsg_manycore source code designed by Bespoke Silicon Group@University of Washington.

The tile based architecture is designed for computing efficiency, scalability and generality. The two main components are:

• Computing Node: In-house RISC-V 32IM compatible core runs at 1.4GHz@16nm, but nodes also can be any other accelerators.
• Mesh Network : Dimension ordered, single flit network with inter-nodes synchronization primitives (mutex, barrier etc.)

Without any customized circuit, a 16nm prototype chip that holds 16x31 tiles on a 4.5x3.4 mm^2 die space achieves 812,350 aggregated CoreMark score.

Initial Setup for running programs

In this directory:

• make checkout_submodules: To update all submodules in imports/.
• make tools: To install software toolchain required running programs on BSG Manycore.
• make machines: Compile simulation executables in machines/.
• Edit BSG_MACHINE_PATH in software/mk/Makefile.paths to choose the machine to run somd programs on.
